Description
Technical field
The present invention relates to the novel high temperature resistance of a kind of gasser, anti-high condensate oil, anti-high salinity foaming water discharge agent and preparation method thereof.
Background technology
Gasser product fluid has two kinds, and one is free-water in stratum or hydro carbons condensed liquid; Two is the Sweet natural gas inflow pit shafts containing steam in stratum, because thermosteresis makes temperature decline gradually along pit shaft, occurs condensation water.If liquid is discharged not in time in pit shaft, then increase shaft bottom back pressure, cause gas production rate constantly to decline.Foam drainage gas recovery technique is one of Main Means of water pumping gas production.It is by foaming water discharge agent at the bottom of the gas well mouth Injection Well of fluid-carrying capability deficiency, to inflate with shaft bottom hydrops by means of the stirring action of natural gas flow and contact, thus reduction surface tension of liquid, produce resistance aqueous foam stable in a large number, obvious reduction gas-liquid mixture density, significantly reduce the friction loss in oil pipe and gravity gradient (effectively reducing sand face pressure), make shaft bottom hydrops be easily carried into ground by air-flow from shaft bottom.Because the feature of its " cost is low, invest little, instant effect, easy and simple to handle " has become the main water drainage-gas recovery technology technology of each Gas Fields.Along with the deep exploitation of gasser, current gas well adopts defeated high temperature, the height of being faced with containing the water pumping gas production such as condensate oil, a high salinity difficult problem, existing usual foam water drainage-gas recovery technology cannot effectively solve, is badly in need of invention a kind of novel high temperature resistance, anti-high condensate oil, anti-high salinity foaming water discharge agent.
Summary of the invention
The object of the invention is the difficulty overcoming prior art, anti-high salinity foaming water discharge agent of the anti-high condensate oil of a kind of high temperature resistance and preparation method thereof is provided, foaming water discharge agent of the present invention has the advantages such as high temperature resistance, anti-high condensate oil, anti-high salinity and fluid-carrying capability are strong, is applicable to all kinds of water-producing gas well.Method of the present invention has simple to operate, equipment and environmental requirement low, easily realize suitability for industrialized production and product cost high.
For achieving the above object, the technical solution used in the present invention is: the anti-high salinity foaming water discharge agent of the anti-high condensate oil of a kind of high temperature resistance, comprises each component of following weight percents:
AMONYL 380LC 60% ~ 40%;
Cocamidopropyl propyl amide hydroxy sulfo lycine 40% ~ 20%;
Cocamidopropyl propyl amide amine oxide 20% ~ 10%;
Water 10% ~ 5%.
The preparation method of the anti-high salinity foaming water discharge agent of the anti-high condensate oil of described high temperature resistance, comprises the following steps:
Each component of following weight percents is added: AMONYL 380LC 60% ~ 40%: cocamidopropyl propyl amide hydroxy sulfo lycine 40% ~ 20%: cocamidopropyl propyl amide amine oxide 20% ~ 10%: water 10% ~ 5% respectively to order in reactor;
At normal temperatures, stir after 30 minutes, in question response still, material fully reacts i.e. obtained described foaming water discharge agent.
As can be seen from every technical characteristic of the invention described above, its advantage is: foaming water discharge agent of the present invention is major ingredient by plant sapogenin glycoside and special surface active agent, with polymer suds-stabilizing agent for auxiliary material, makes through polymerization, complex process.Can high temperature resistance (120 DEG C), anti-high condensate oil (50%), anti-high salinity (250000ppm), outward appearance is colourless or light yellow liquid, free from extraneous odour.Method of the present invention has simple to operate, equipment and environmental requirement low, easily realize suitability for industrialized production and product cost high.The present invention is applicable to all kinds of water-producing gas well.
